METALLIC TRUCK FOR RAlLROAD-CARS.

Specification of Letters Patent.

Patented Jan. 8, 1907.

Application filed May 15, 1 906. $erial No 316.913-

TOIIIZZ 1071,0722, it may concern:

Be it known that I, FREDRIOH GEBHARDT, a citizen of the United States, and a resident of Alliance, in the county of Stark and State of Ohio, have invented a new and Improved Metallic Truck for Railroad-Cars, of which the following is a full, clear, and exact description.

The invention relates to metallic trucks for railroad-cars such as shown and described iii the application for Letters Patent of the United States, Serial No. 27 0,787 filed by me on July 22, 1905.

The object of the present invention is to provide a new and improved metallic truck or railroad-cars which is exceedingly strong and durable and arranged to provide a solid bed for the car-body to rest on and to readily accommodate the draw-bar timbers.

The invention consistsof novel features and parts and combinations of the same, which will be more fully described hereinafter and their pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indi cate corresponding parts in all the views.

Figure 1 is a plan view of the improvement. Fig. 2 1s a sectional side elevation of the same on the line 2 .2 of Fig. 1. Fig. 3 is an enlarged transverse section of the same on the line 3 3 of Fig. 1. Fig. 4 is an inverted plan view of the body-bolster. Fig. 5 is a plan view of part of the truclvbolster, and

Fig. 6 is a sectional plan view ofthe journalbox in position on the side frame.

The metallic side frames A are integrally connected with ea ch other by a channel crossbar B, having flanges B fastened by bolts C to the inner faces of the side frames A adj acent to the vertical guideways A, formed in the side frames A at the middle thereof and from the top in a downward direction, as plainly illustrated in the drawings; The cross-bar B has its terminals B extending into and resting on the bot-toms of the guideays A, and the said terminals B are rigidly secured to the said bottoms of the guideways A by bolts C, the heads of which are countersunk in the upper faces of the termi-I nals B minals B On the upper surfaces of the terare mounted to rock in a transverse direction the seats D, each supporting the lower ends of a number of sprin$ E en gaged at their upper ends by a seat simibricant passing lar to the corresponding seat D, and each of the seats 1) is mounted to rock on the under side of the end F of a truck-bolster F, provided at its upper surface and at the middle of the bolster with an annular bearing or seat F engaging with an annular pivot G, formed on the under side of the body-bolster G, secured in the usual manner to the under side of the car-body of a railroad-ear. Each of the side frames A is provided at its outer ends with a journal-box H, in which are mounted to turn the journals of the axles I,- carrying the usual car-wheel J.

The body-bolster G is provided at its niiddle with a longitudinally-extending integral I pocket/G for receiving the draw-bar timber K, and on the said body-bolster G are integrally-forined verticallydisposed flanges G on which are bolted or otherwise secured the ends of longitudinally-extending beams L, flush on the top with. the upper surface of the body-bolster G, so as to form with the latter a solid bed for the car-body of a railroad-can.

The flanges G are provided with. lateral offset lower edges adapted to support the lower edge of the longitudinally-extending beams L, as shown in Fig. 3.

It is understood that the pocket G extends in a forward direction, while the flanges G extend rearwardly and the beams L are socured to the flanges G of the front and rear trucks of acar to rigidly connect the two body-bolsters G with each other and form a bed for the car body, as before mentioned.

On the body-bolster G directly above the pivot G is arranged an integral oil-well G for containing oil, grease, or other lubricant,

and from the bottom of this oil-well G lead apertures G to the under sideof' the pivot G, the apertures G opening into radial grooves G, formed on the under side of the pivot G. In the bottom of the bearing F engaged by the pivot G, are formed concentric annular grooves F 1*, connected with each other at intervals by radial grooves F so that the lufrom the oil-well G down through the apertures G and into tl.

radial grooves G is readily distributed to the groovesF F, and F iii-the bearing F to in;

sure a proper lubrication of the pivot G in the bearing F On the top of the truck bolster F are formed the track-surfaces F, on which are mounted to travel friction-rollers G journaled in pockets G depending intcgrally from bolster G, as plainly shown in Fig. 3.

the under side of the body-- 4I ment, and the lateral movement of the jourseats or bearings B The spring-seats D D and the terminals B and F of the cross-bar B and the truck-' bolster ,F are provided at their side edges with recesses engaging vertically-disposedribs A arranged integrally on the side walls of the guideways A, and the terminalF of the truck-bolster -F is limited in its upward movement by a yoke N, extending across the open top of the guideway A and secured by bolts 0 to the side frames A, cated in Figs. 1, 2, and 3. Each of theyoke's N is provided at its top with a longitudinallyextending strengthening-rib N, and the, under side of eachv yoke is provided'with' transversely-extending dovetail-tongues N engaging correspondingly shaped dovetailgrooves in the upper'faces of the side frames A. Each of the spring-seats D D"-is provided at its middle with a longitudinally-ex-' tending half-round pivot D D engaging formed in thecorre-- iponding terminals B F. The spring-seats and D are also provided at their front and rear ends with short flanges D D to limit the rocking movement of the said seats by abutting'against the" corresponding faces of the" Each of the j0urnal-' terminals B and F. boxes H is provided at both sides withven' tic'ally disposed ribs H, of which one fits a corresponding recess inthe'inn'er wall of the seat of the journal-box H in the end of the side frame A, it being understood that by the arrangement described the j ournal-boxes H can bereadily used or interchanged at either end of the side frameA, as the'corresponding rib H fits the corresponding recess on the'in-- nerwall of the 'seat in the side frame A. Bolts H secured to the terminals of the 'side'frame A, engage the outer sides of the journal-boxes H to hold thesameagainst outward movenal-boxes is prevented by theusual lugs H engaging the front and rear faces of the side frames A.

' Inorder to give added strength to the side fraines A, truss ribs A extend integrally u ward and outward from'the lower ends of the guideways A, as shown in Fig. 2, to relieve theyokes N of undue strain exerted length-- Wise of the side frames A against thesides'of theguideways A from the'car-axles by way of thejournaLboxes'Hj The'body-bolst'er G is alsoprovided'with truss-ribs G to'reinforce and strengthen the'said body-bolster.-

From theforegoing it will be seen that the as plainly indi- By"the 'use of the beams L an "on; andby "truck' is formed of comparatively few parts,

which can be readily assembled and constitutean exceedin lystrong and durable truck. 'Bymounting the ody bolsterGon the truck- 'bolster F in the manner described all friction is reduced-to a minimum, and hence cars provided with the improved trucks can readily run around curves without undue friction be- .tween the truck-bolster and the car-bolster.-

It will also be noticed that by having the spring-seats D D mounted to rock in a transverse 'direction the side frames A and the truck-bolster F are relieved of undue strain. exceedingly solid bedis provided forthecar-body to rest bolster G proper means are furnished for supporting the timbers of the drawbar. 4

Having thus described my invention, I

claim as new and" desire to 'se'cure'by-Letters Patent 1. A metallic truckfor railroad-cars hav ing'a side frame provided at each end with a seat "for the journal-box, the inner wall of the said seat being recessed, and a journal-box having lugs on each side and adapted to fit I the said recess to allow interchange of a box on either seat.

2. A car-bolster having a flat upper surface, a pocket extending laterally from-the central ortionof said bolster adapted to receive a raw-beam timber, the upper surface of the pocket beingflush with the upper suraving the pocket G on thecarface of the*b'olster, and vertical flan es extending fro'm'theopposite side of the olster provided With'ofi'set lower edges adapted to support the side beams of acar-body.

3. A car-bolster having a flat upper surface, a pocket adapted to receive a draw-- beam timber extending laterally from the FREDRICH GEBHARDT.
